Right. > Hence why not simplifying its interface and remove the force flag? One point to note is that the signature and usage of UpdateMinRecoveryPoint() is same as it was when it got introduced in commit-cdd46c76. Now the only reasons that come to my mind for introducing the force parameter was (a) it looks cleaner that way to committer (b) they have some usecase for the same in mind (c) it got have overlooked. Now, if it got introduced due to (c), then your patch does the right thing by removing it. Personally, I feel overloading the parameter for multiple purposes makes code less maintainable, so retaining as it is in HEAD has some merits. -- With Regards, Amit Kapila.
